Codes in packaging is one of the thing that fascinate me the most. I spent the entirety of my master degree year studying it. I tried to find the most common food item to see if the packaging would be the same in every country of the world. So, during Covid I did a little annoucement on various plateforms and asked people from around the world to send me an empty carton of milk. When I received them, I shot them in a studio and place them all side by side to compare them and to be abble to really see the similarities.
